Release Notes for Android SDK - 9.x

9.6.60 (12/23/2025)

This release includes security maintenance updates to ensure continued protection of the product.

Security Updates

  • Updated third-party libraries to incorporate the latest security fixes.

9.6.50 (09/23/2025)

New

  • Supported 16 KB page sizes

9.6.40 (03/21/2024)

Improved

  • Updated the security of the DynamsoftBarcodeReader library and other corresponding dependent libraries.
  • Improved the multi-thread processing logic of concurrent instance licenses.
  • Improved the barcode decoding performance:
    • Improved the accuracy when decoding OneD & PDF417 barcodes.
    • Improved the readability of dense DataMatrix codes.

Changed

  • Added a new error code DM_LICENSE_CACHE_USED, which is returned when failing to connect to the license server but a valid license cache is available. Error codes DM_FAILED_TO_REACH_DLS and DM_LICENSE_SYNC_FAILED are no longer returned in this scenario.

Fixed

  • Fixed crash bugs in the barcode decoding algorithm.
  • Fixed a bug where the location of the barcode result(s) might be incorrect.

9.6.20 (03/16/2023)

Fixed

  • Fixed a bug where license authorization may fail when the main license server is not available.
  • Other small fixes and tweaks.

9.6.11 (01/16/2023)

Fixed

9.6.10 (01/10/2023)

Fixed

  • Fixed a bug that some OneD barcodes without start & stop characters are not decoded when parameter RequireStartStopChars is set to 0.
  • Fixed a crash bug by adding protection in algorithm.

Improved

  • Improved the performance of Direct Part Marking (DPM) barcode decoding.
  • Improved the performance of GS1 Databar barcode decoding.

9.6.0 (12/13/2022)

Version Highlights

  • Image orientation handling is supported by a new feature. With the new feature, you can:
    • Get a TranformationMatrix along with the barcode location result.
    • Implement coordinates transformation on the barcode location result with the TransformationMatrix.
  • DotCode decoding is improved by optimizing the localization of DotCodes that are close to one another.

auto-zoom

  • EAN8 barcode decoding is improved by honing the accuracy of localization algorithms.
  • QR code localizing is improved by reducing the mis-assemble rate of the finder patterns when using the localization mode LM_CONNECTED_BLOCK or LM_SCAN_DIRECTLY, which are designed for speed. The mis-assembling only occurs when there exist dense QR codes on the same image.
  • Mirrored rectangular DataMatrix barcode is supported by implementing MirrorMode when localizing the barcodes.

auto-zoom

  • Deformed barcode decoding is improved by extending the supported modes and mode arguments of DeformationResistingModes.

Changelog

New

  • Added a new method setLogConfig so that user can get log information of the algorithm. Enumeration EnumLogMode is added so that users can set whether to save the log information.
  • Enabled decoding methods decodeFile, decodeFileinMemory and decodeBase64String to read EXIF data of the given image so that the library can obtain the orientation information when processing image file.
  • Override method decodeBuffer. You can input an ImageData object as the barcode decoding parameter. The library can obtain the orientation information from the ImageData object.
  • Added a new property transformationMatrix to class LocalizationResult so that the library can output a transformation matrix for users to transform the coordinates of the barcode result.
  • Added a new method setDuplicateForgetTime to filter out all duplicate barcode results for a period of time when processing video streaming.
  • Added new properties hasLeftRowIndicator and hasRightRowIndicator to class PDF417Details to return whether the left or right row indicator of the PDF417 barcode is detected.
  • Added a new member BF2_ALL to enumeration BarcodeFormatIds_2.
  • Extended the features of DeformationResistingModes:
    • Extended the valid mode arguments of DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE with two new arguments: GrayscaleEnhancementMode and BinarizationMode.
    • Support mode DRM_AUTO.

Improved

  • Improved the accuracy when processing multiple QR codes.
  • Improved the processing speed by excluding incorrectly located barcode zones before decoding.
  • Improved the creation, destruction, and acquisition logic of concurrent instances.
  • Improved the scan count of duplicate barcodes when the Charge Way is per scan.
  • Improved the accuracy of EAN8 localization result(s).
  • Improved the localization of mirrored DataMatrix barcode by implementing MirrorMode.

Fixed

  • Fixed a bug that DotCodes might not be decoded when they are densely arranged.
  • Fixed a crash bug when trying to output a template which includes customized value for parameterd BarcodeTextRegEexPattern.
  • Fixed a bug that might cause memory churn when the instance/thread was created frequently.

Removed

  • Removed destroy from class BarcodeReader.

9.4.0 (11/04/2022)

Version Highlights

  • DotCode decoding has been improved by optimizing the localization and decoding algorithm.
  • Stacked, skewed or perspective distorted OneD barcode decoding has been improved.

Changelog

New

  • Added an argument IsOneDStacked to LM_SCAN_DIRECTLY to process stacked OneD barcodes.
  • Added a parameter PatchCodeSearchingMargins to specify the searching area of PatchCode.
  • Added the supported data format of FormatSpecification.PartitionModes to enhance the readability of the parameters. Users can use a list of enumeration names to specify the PartitionModes.

Improved

  • Improved the localization mode LM_LINES to better support skewed and perspective OneD barcodes.
  • Enhanced tamper resistance of the license keys so that any change to the license string makes it invalid.

Deprecated

9.2.10 (06/28/2022)

Version Highlights

  • Barcode boundary-seeking algorithm is refactored to improve stability.
  • Pharmacode decoding is optimized to improve accuracy.
  • The function of device-alias is added to allow users to give each device a readable name. For end-users and administrators, this makes it more friendly to distinguish between devices about license usage statistics.

Changelog

New

9.0.2 (05/26/2022)

New

  • Added the following property/Method to iImageData class:
    • toBitmap: The method that can convert the ImageData to a Bitmap.

9.0.1 (04/20/2022)

Fixed

  • Fixed a bug that might offset the position of highlight overlays on the decoded barcodes when used together with DynamsoftCameraEnhancer.
